[1] The Chahamanas were originally feudatories to the Gurjara-Pratiharas, but Simharaja had assumed the title Maharajadhiraja taking advantage of their decline.
[5] The Chahamana chronicle Prithviraja Vijaya, which describes the Chaulukyas of Gujarat as "Gurjaras", states that Mularaja fled to Kantha-durga (modern Kanthkot) during Vigraharaja's invasion.
Sapadalaksha was the Chahamana territory, while Tilanga here refers to the kingdom of the Kalyani Chalukya ruler Tailapa II.
Mularaja moved to the Kantha-durga, and hoped that the Sapadalaksha ruler would return to his capital Shakambhari to worship his family goddess Ashapuri during the festival.
[6] Dasharatha Sharma also theorized that Vigraharaja had the upper hand in the conflict, as even Merutunga agrees that Mularaja had to take shelter in the Kantha-durga.
[5][7] According to Prithviraja Vijaya, Vigraharaja marched to the region around the Narmada river, and subjugated a king of the lunar dynasty.
After his victory, he built a temple dedicated to the goddess Ashapuri at Bhrigukachchha (modern Bharuch), on the banks of Narmada.
[8] According to Dasharatha Sharma, one possibility is that Vigraharaja allied with Barapa to defeat the Gujarat Chaulukya king Mularaja, but this is only a conjecture.
This inscription records the grant of two villages by the king for maintaining the temple dedicated to the deity Harsha-deva.
